Field of the Invention
[0001] The present invention relates to a lipstick case structure, and more particularly,
to a slide type lipstick case structure which is configured wherein a protection cap
adapted to surround the outer periphery of a lipstick is coupled to a body through
a triple spiral in such a manner as to be moved up and down by means of rotation manipulations,
thereby allowing the lipstick to be extracted out of the body and to be retracted
into the body.
Background Information
[0002] Generally, a lipstick, which is one of cosmetic products used for making a user's
face look beautiful, is generally mounted into a case adapted to allow the lipstick
to be moved up and down manually, and so as to use the lipstick, a cover of the lipstick
case structure is open to make the lipstick extracted out of the interior of the case.
According to the typical lipstick case structure, if a lower tube is rotated in a
state where a lipstick-inserted tube is taken by a user's fingers, a rotary tube disposed
at the inside of the lower tube is rotated so that guide protrusions of the lipstick-inserted
tube are moved up and down along spiral grooves formed on a guide tube to cause the
lipstick to be extracted out of the lipstick-inserted tube and to be retracted into
the lipstick-inserted tube. Next, the lipstick extracted from the top end periphery
of the lipstick-inserted tube is applied to the user's lips.
[0003] The lipstick, one of cosmetic products for make-up, is applied to lips, and thus,
the lipstick is mounted in the case for coloring the lips directly or by means of
a separate brush rod.
[0004] The lipstick case structure is twistedly rotated to cause the lipstick to be moved
up from the interior of a case and at the same time to be extracted out of the front
end periphery of the case, thereby applying the lipstick protruded from the case to
the lips. In this case, a separate inner case is inserted into the case, that is,
an outer case, so that the lipstick can be moved up and down from the outer case through
the coupling structure between the outer case and the inner case.
[0005] Moreover, the outer case is made with various colors and designs, thereby satisfying
a user's various preferences.
[0006] FIG.1 is a separate perspective view showing a lipstick case structure of the prior
art. As shown in FIG.1, the lipstick case structure of the prior art largely includes
a holder 10, a guide tube 20, and a rotary tube 30, and further has a lower case 40
coupled to the lower outer periphery of the guide tube 20 if necessary and a cover
50 coupled to the upper outer periphery of the guide tube 20.
[0007] At this time, the holder 10 has a lipstick 12 having various colors and shapes mounted
on the top side thereof, and it further has two elevating protrusions 11 formed on
both sides of the outer periphery thereof.
[0008] The guide tube 20 has vertical guide slots formed on both sides thereof.
[0009] The rotary tube 30 has a spiral groove 31 formed on the inner periphery thereof.
[0010] Accordingly, the holder 10 is inserted into the guide tube 20 in such a manner as
to allow the elevating protrusions 11 thereof to be inserted into the guide slots
21 of the guide tube 20, and the rotary tube 30 is inserted into the outside of the
guide tube 20 in such a manner as to allow the elevating protrusions 11 of the holder
10 protruded through the guide slots 21 to be located in the spiral groove 31 thereof.
[0011] In the above-mentioned coupling state, as a result, if the guide tube 20 or the rotary
tube 30 is twistedly rotated or both of them are twistedly rotated in opposite directions
to each other, the holder 10 is moved up and down inside the guide tube 20, and the
lipstick 12 is extracted out of the guide tube 20 and is retracted into the guide
tube 20.
[0012] If the rotary tube 30 is rotated in one side direction thereof, the spiral groove
31 is rotated to cause the elevating protrusions 11 located in the spiral groove 31
to be moved up along the inclined portion of the spiral groove 31. Since the elevating
protrusions 11 are located in the guide slots 21, they are moved up only within the
range of the interior of the guide slots 21 to cause the lipstick 12 to be protruded
in a vertical direction.
[0013] The lipstick case structure of the prior art having the above-mentioned operating
configuration is operated to convert the rotary motions of the guide tube 20 and the
rotary tube 30 into the linear motion of the holder 10, thereby allowing the lipstick
12 to be extracted out of the guide tube 20 and to be retracted into the guide tube
20.
[0014] However, the conventional lipstick case structure is made by coupling a plurality
of parts like the holder 10, the guide tube 20, the rotary tube 30 and the lower case
40, which causes the manufacturing cost thereof to be undesirably raised.
[0015] Further, the coupling of the plurality of parts causes the man hours to be increased
to make the productivity undesirably deteriorated.
Summary of the Invention
[0016] Accordingly, the present invention has been made in view of the above-mentioned problems
occurring in the prior art, and it is an object of the present invention to provide
a slide type lipstick case structure which is configured wherein a protection cap

Detailed Description of the preferred embodiments
[0029] Hereinafter, an explanation on a slide type lipstick case structure according to
the preferred embodiments of the present invention will be given with reference to
the attached drawings.
[0030] FIG.2 is a perspective view showing an assembled state of a slide type lipstick case
structure according to a first embodiment of the present invention, FIG.3 is a perspective
view showing a separated state of a cover from the slide type lipstick case structure
according to the first embodiment of the present invention, and FIG.4 is a perspective
view showing the open state of a lipstick from the slide type lipstick case structure
according to the first embodiment of the present invention.
[0031] Referring to FIGS.2 to 4, the slide type lipstick case structure according to the
first embodiment of the present invention includes: a body 100 into which a lipstick
400 is mounted, a protection cap 200 coupled to the outer periphery of the body 100
through a triple spiral in such a manner as to be moved up and down by means of rotation
manipulations, thereby allowing the lipstick 400 to be extracted out of the body 100
and retracted into the body 100, and a cover 300 adapted to open and close the upper
portion of the body 100 into which the protection cap 200 is mounted.
[0032] FIGS.5a and 5b are a sectional view and an enlarged view showing the main parts of
the slide type lipstick case structure according to the first embodiment of the present
invention. Referring to FIGS.5a and 5b, the body 100 has a mounting portion 130 formed
on the center thereof to mount the lipstick 400 thereinto. At this time, as shown,
the mounting portion 130 has a shape of a hopper having an upper diameter larger than
a lower diameter thereof. Such hopper-shaped mounting portion 130 is capable of mounting
the lipstick 400 therein, without having a separate support plate.
[0033] For example, the whole diameter of the lipstick 400 is similar to the upper diameter
of the hopper-shaped mounting portion 130, and thus, even though the lipstick 400
is pushed toward the body 100 by means of the pressure caused at the time of coloring
lips, it is not pushed further by the inclined face of the hopper-shaped mounting
portion 130.
[0034] Accordingly, the lower portion of the hopper-shaped mounting portion 130 is formed
of a hollow tube, which minimizes the volume of the body 100 and reduces the material
cost thereof. Further, the body 100 has a spiral groove formed on the outer periphery
thereof, to which the protection cap 200 is coupled spirally. In this case, the protection
cap 200 has a guide protrusion formed on the inner periphery thereof, to which the
spiral groove of the body 100 is coupled. Of course, the body 100 may have the guide
protrusion, and the protection cap 200 may have the spiral groove.
[0035] The protection cap 200 is spirally coupled to the body 100 in such a manner as to
be moved up and down, and so as to prevent the escape from the body 100, the protection
cap 200 has an escape prevention structure. For example, a prevention projection may
be formed to allow the protection cap 200 and the body 100 to be engaged with each
other, thereby preventing the protection cap 200 from escaping from the body 100.
[0036] The prevention projection may be formed on the top periphery of the body 100 and
the bottom periphery of the protection cap 200 in such a manner as to face each other.
Desirably, the prevention projection has a shape capable of climbing over each other
by the application of an external force, for example, has a hemispherical section.
[0037] Further, as shown in FIGS.5a and 5b, the body 100 has a double tube structure wherein
an inner tube 120 and an outer tube 110 are spaced apart from each other by a given
distance.
[0038] At this time, an elevating passage 140 is formed between the inner tube 120 and the
outer tube 110, along which the protection cap 200 is moved up and down in the state
of being spirally coupled thereto. The elevating passage 140 is closed on the underside
thereof and is open on the top thereof.
[0039] Escape prevention means 160 is formed on the elevating passage 140 in such a manner
as to be engaged with the lower end of the protection cap 200, thereby preventing
the protection cap 200 from escaping from the body 100. The escape prevention means
160 is formed of a round protrusion having a hemispherical section.
[0040] The escape prevention means 160 is formed on any of the outer peripheral surface
of the inner tube 120 and the inner peripheral surface of the outer tube 110.
[0041] The inner tube 120 has the mounting portion 130 formed on the center portion thereof
to mount the lipstick 400 thereinto, and the mounting portion 130 has a shape of a
hopper having an upper diameter larger than a lower diameter thereof. The lower portion
of the hopper-shaped mounting portion 130 is formed of a hollow tube.
[0042] The protection cap 200 is spirally coupled directly to the outer periphery of the
body 100 in such a manner as to be moved up and down by means of rotation manipulations,
thereby allowing the lipstick 400 to be extracted out of the body 100 and retracted
into the body 100. The protection cap 200 is formed of a hollow tube and has an escape
prevention lip 210 formed along the lower end periphery thereof when the lipstick
case structure is vertically upright.
[0043] The escape prevention lip 210 is engaged with the escape prevention means 160 formed
on the body 100, thereby preventing the protection cap 200 from escaping from the
body 100, and the escape prevention lip 210 is formed of a round protrusion having
a hemispherical section.
[0044] The escape prevention lip 210 is formed on any of the outer and inner peripheral
surfaces of the protection cap 200.
[0045] So as to perform the spiral coupling between the protection cap 200 and the body
100, additionally, a spiral groove and a guide projection for coupling to the spiral
groove are formed. For example, a spiral groove 150 is formed on any of the outer
peripheral surface of the inner tube 120 and the inner peripheral surface of the outer
tube 110, and a guide projection 220 is formed on any of the outer and inner peripheral
surfaces of the protection cap 200.
[0046] Also, the outer tube 110 has a round stepped portion 170 formed along the top end
periphery thereof in such a manner as to be detachably coupled to the bottom end periphery
of the cover 300. The stepped portion 170 and the top end periphery of the cover 300
are press-fitted to each other.
[0047] For example, a round protrusion (not shown) is formed along the stepped portion 170,
and a round protrusion (not shown) is formed along the top end periphery of the cover
300 correspondingly to the round protrusion of the stepped portion 170, so that the
protrusions are engaged with each other to prevent the cover 300 from escaping from
the outer tube 110. FIGS.6a and 6b are a sectional view and an enlarged view showing
the main parts of a slide type lipstick case structure according to a second embodiment
of the present invention. Referring to FIGS.6a and 6b, the configuration of the second
embodiment of the present invention is almost similar to that of the first embodiment
of the present invention, except that the outer tube 110 has a fastening ring 500
formed along the top end periphery thereof in such a manner as to be engaged with
the lower end periphery of the protection cap 200, thereby preventing the protection
cap 200 from escaping from the outer tube 110.
[0048] For example, the forced coupling structure made by the escape prevention means 160
and the escape prevention lip 210 can be adopted when the body 100 and the protection
cap 200 are made of a deformable soft material like a synthetic resin, and accordingly,
the forced coupling structure cannot be used when they are made of a material having
low deformity such as a metal material, glass and the like.
[0049] Accordingly, as shown in FIGS.6a and 6b, the escape prevention lip 210 is formed
along the lower end periphery of the protection cap 200, and the outer tube 110 has
the fastening ring 500 formed along the top end periphery thereof, the fastening ring
500 having an inside protrusion formed to be located on top of the escape prevention
lip 210.
[0050] At this time, the fastening ring 500 has a round stepped portion formed along the
top end periphery thereof in such a manner as to be detachably coupled to the lower
end periphery of the cover 300. The stepped portion and the top end periphery of the
cover 300 are press-fitted to each other.
[0051] For example, a round protrusion (not shown) is formed along the stepped portion,
and a round protrusion (not shown) is formed along the top end periphery of the cover
300 correspondingly to the round protrusion of the stepped portion, so that the protrusions
are engaged with each other to prevent the cover 300 from escaping from the outer
tube 110.
[0052] The cover 300 is adapted to open and close the top portion of the body 100 into which
the protection cap 200 is mounted and is made of a transparent material so that the
lipstick 400 mounted can be seen from the outside.
[0053] FIGS.8a and 8b are a perspective view and an enlarged view of the main parts of a
protection cap of a slide type lipstick case structure according to a third embodiment
of the present invention, and FIGS.9a and 9b are a perspective view and a bottom view
showing a body in the slide type lipstick case structure according to the third embodiment
of the present invention.
[0054] Referring to FIGS.8a to 9b, the configuration of the third embodiment of the present
invention is almost similar to that of the first embodiment of the present invention,
except that a spiral groove 230 is formed on any of the outer and inner peripheral
surfaces of the protection cap 200 and a guide projection 121 is formed on any of
the outer peripheral surface of the inner tube 120 and the inner peripheral surface
of the outer tube 110 in such a manner as to be received with the spiral groove 230
of the protection cap 200.
[0055] At this time, as shown in FIGS.8a and 8b, the protection cap 200 has an inclined
guide portion 250 formed on a portion from which the lower end portion spiral groove
230 starts, so that the guide protrusion 121 climbs over the inclined face of the
inclined guide portion 250 and is received into the spiral groove 230, thereby preventing
the escape from the protection cap 200 in a reverse direction.
[0056] Further, as shown in FIGS.9a and 9b, in case where the guide protrusion 121 is formed
on the body 100, a portion of the bottom surface of the body 100 is formed open to
allow molding to be easily carried out.
[0057] Moreover, the mounting portion 130 in which the lipstick 400 is mounted has a partition
131 formed thereon, and the structure of the partition 131 can be applied to the first
and second embodiments of the present invention.
[0058] FIG.7 is a perspective view showing a spiral groove in the slide type lipstick case
structure according to the second embodiment of the present invention, and as shown,
the spiral groove and the guide protrusion in the first to third embodiments of the
present invention have a triple spiral coupling structure where they are formed at
the same time in three directions.
[0059] As mentioned above, the slide type lipstick case structure according to the preferred
embodiments of the present invention is configured wherein the protection cap adapted
to surround the outer periphery of the lipstick is directly coupled to the body through
a triple spiral in such a manner as to be moved up and down by means of rotation manipulations,
thereby allowing the lipstick to be extracted out of the body and to be retracted
into the body, so that the extracting and retracting operations of the lipstick can
be achieved just with the simple combination of the protection cap and the body. As
a result, the number of parts used is substantially decreased to permit the manufacturing
cost to be lowered, and further, the man hours for assembling are shortened to improve
the productivity.
